I finally got my snare procing spear () at 4th attempt, all you need is one knight friend to duo Xygoz (cannot be soloed by a shamy due to fear).
Even feared about 75% of the time I was easily able to heal a knight friend with fearless AA (I did it with 80 sk, 80 paly and 77 paly).
To speed up things I had a 55 mage alt at Xygoz (he was indiff) for CotH purposes (just remember to move him out of AE radius, mine died of that).
Remember also to use shamy pet for more dps, he cannot be feared
